CVE-2025-4502: Campcodes Sales And Inventory System SQLi

CVE-2025-4502 Overview

A critical SQL injection vulnerability has been identified in Campcodes Sales and Inventory System version 1.0. This vulnerability exists in the /pages/creditor_add.php file where improper handling of user input allows attackers to inject malicious SQL commands. The attack can be initiated remotely without authentication, potentially allowing unauthorized access to sensitive database information, data manipulation, or complete database compromise.

Critical Impact
Remote attackers can exploit this SQL injection vulnerability to extract, modify, or delete sensitive business data including sales records, inventory information, and creditor details from the affected system.

Technical Details for CVE-2025-4502

Vulnerability Analysis

This SQL injection vulnerability in Campcodes Sales and Inventory System stems from inadequate input validation in the creditor management functionality. The /pages/creditor_add.php endpoint processes user-supplied data without proper sanitization before incorporating it into SQL queries. This allows an attacker to manipulate the intended SQL logic by injecting malicious SQL statements through form parameters or request inputs.

The vulnerability is classified under CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component), which encompasses injection flaws where user input is not properly validated before being processed by an interpreter.

Root Cause

The root cause of this vulnerability is the failure to implement proper input sanitization and parameterized queries in the creditor_add.php file. The application directly concatenates user-supplied input into SQL statements without escaping special characters or using prepared statements. This design flaw allows attackers to break out of the intended query context and execute arbitrary SQL commands against the backend database.

Attack Vector

The attack vector is network-based, allowing remote exploitation without requiring authentication or user interaction. An attacker can craft malicious HTTP requests containing SQL injection payloads targeting the creditor addition functionality. The low complexity of the attack means that standard SQL injection techniques can be employed to exploit this vulnerability.

The vulnerability mechanism involves manipulating input parameters sent to /pages/creditor_add.php. When the application constructs SQL queries using unsanitized user input, attackers can inject SQL metacharacters and additional SQL statements. This can lead to unauthorized data retrieval, data modification, authentication bypass, or in severe cases, command execution on the underlying database server. For detailed technical analysis, refer to the GitHub Issue Tracking CVE and VulDB entry #308218.

Detection Methods for CVE-2025-4502

Indicators of Compromise

Unusual or malformed HTTP requests to /pages/creditor_add.php containing SQL syntax characters such as single quotes, semicolons, or SQL keywords
Database error messages in application logs indicating SQL syntax errors or unexpected query results
Unexplained database queries or data modifications in audit logs
Web server access logs showing requests with encoded SQL injection payloads targeting creditor-related endpoints

Detection Strategies

Implement Web Application Firewall (WAF) rules to detect and block common SQL injection patterns targeting the affected endpoint
Deploy intrusion detection systems (IDS) with signatures for SQL injection attack patterns
Monitor application and database logs for anomalous query patterns or authentication failures
Use SentinelOne Singularity Platform to detect exploitation attempts and post-exploitation activities on systems hosting this application

Monitoring Recommendations

Enable verbose logging on the web application server to capture all requests to /pages/creditor_add.php
Configure database auditing to log all queries executed against the application database
Set up alerts for multiple failed SQL queries or unusual query execution times that may indicate injection attempts
Regularly review access logs for patterns consistent with automated SQL injection scanning tools

How to Mitigate CVE-2025-4502

Immediate Actions Required

Restrict access to the /pages/creditor_add.php endpoint to trusted IP addresses only until a patch is available
Implement input validation at the web server level using WAF rules to filter SQL injection payloads
Consider temporarily disabling the creditor addition functionality if not critical to business operations
Review database permissions to ensure the application uses least-privilege database accounts

Patch Information

At the time of publication, no official patch has been released by Campcodes for this vulnerability. Users are advised to monitor the CampCodes website for security updates and apply patches immediately when available. For tracking purposes, refer to VulDB entry #308218 for updated remediation information.

Workarounds

Implement prepared statements or parameterized queries in the creditor_add.php file by modifying the source code
Deploy a web application firewall (WAF) in front of the application configured to block SQL injection attempts
Use stored procedures with proper parameter binding instead of dynamic SQL queries
Apply network segmentation to isolate the vulnerable application from critical systems

bash

# Example WAF rule for ModSecurity to block SQL injection attempts
SecRule REQUEST_URI "/pages/creditor_add.php" "id:1001,phase:2,deny,status:403,msg:'Potential SQL Injection',chain"
SecRule ARGS "@detectSQLi" "setvar:tx.sql_injection_score=+1"
